[0003] This sheet metal bending machine has high manual labor intensity and unstable quality. Therefore, it is necessary to provide a subject to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the embodiments of the present utility model is to provide a subject matter to solve the problems in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A sheet metal bending automatic feeding device, characterized by comprising:

[0007] A bending machine, wherein a material storage is installed in the bending machine;

[0008] The gantry-type truss material-retrieving manipulator is installed above the material storage with a sliding connection and a grabbing suction cup installed on the surface;

[0009] The conveying and positioning turntable is installed on the left side of the material warehouse and below the lifting gantry truss material retrieving manipulator, and is used to position and convey the sheet materials;

[0010] The auxiliary support device is fixed at the front end of the bending machine to ensure that the bending quality of longer sheets is not affected by their own weight and insufficient rigidity.

[0011] Furthermore, the material storage includes a material picking platform installed on the inner side of the bending machine, the material picking platform is made of welded steel and is used for stacking sheet materials; a magnetic plate separator is installed on the material picking platform, and is used when the gantry truss material picking robot is ready to pick up materials above the material picking platform. The magnetic plate separator receives a signal and separates the stacked plates in the vertical direction through the magnetic field force.

[0012] Furthermore, the conveying and positioning turntable includes a conveying walking mechanism, which is slidably connected to the bending machine and has a rack installed on the side; a walking mechanism driving motor, which is installed on the bending machine, and a gear is installed at the output end of the walking mechanism driving motor, and the gear and the rack are meshingly connected; a linear cylinder, which is installed on the conveying walking mechanism, and the output end of the linear cylinder is connected to a movable locator through a telescopic rod; a lifting cylinder, which is installed on the conveying walking mechanism, and a vacuum suction cup is installed at the output end of the lifting cylinder.

[0013] Furthermore, the auxiliary supporting device includes a rotating shaft seat, which is hinged on the bending machine and has a supporting arm installed on the side; a turning cylinder, which is installed on the bending machine, and the supporting arm is connected to the output end of the turning cylinder.

[0014] Furthermore, a turning arm is installed on the right side of the conveying and positioning turntable, and the turning arm is used to drive the sheet material to turn over.

[0015] Compared with the prior art, the embodiments of the utility model have the following beneficial effects: the utility model sets a gantry truss material-retrieving manipulator, which is slidably connected and installed above the material warehouse, and has a grabbing suction cup installed on the surface; a conveying and positioning turntable is installed on the left side of the material warehouse and below the lifting gantry truss material-retrieving manipulator, which is used to position and convey the sheet material; an auxiliary supporting device is fixed at the front end of the bending machine, which is used to ensure that the bending quality of longer sheets is not affected by their own weight and insufficient rigidity.

[0016] When the sheet material is in use, the gantry truss material-taking robot descends above the material warehouse and absorbs the first sheet material above the material warehouse through the suction cup. The magnetic plate separator in the material warehouse separates the first sheet bonded together below through the magnetic field force, ensuring that the gantry truss robot takes the first sheet and moves it above the conveying and positioning turntable, and places the material on the conveying and positioning turntable. The movable positioner is displaced according to different sheets under the drive of the linear cylinder, and the sheet material is clamped and positioned at the center of the turntable through the displacement of the positioner. The conveying and positioning turntable is driven by the walking mechanism to send the sheet material to the bending machine for bending. During the bending process, the auxiliary supporting mechanism drives the supporting arm to ensure that the sheet material will not sag due to excessive length during the bending process, thereby ensuring the quality. After completing this step of bending, the suction cup on the conveying and positioning turntable rises and sucks the sheet material, and then the conveying and positioning turntable returns under the drive of the walking mechanism.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figure 1 to Figure 4 , a sheet metal bending automatic feeding equipment, comprising:

[0027] A bending machine 10, wherein a material storage 1 is installed in the bending machine 10;

[0028] The gantry-type truss material-retrieving manipulator 2 is slidably connected and installed above the material storage 1, and a grabbing suction cup is installed on the surface;

[0029] The conveying and positioning turntable 3 is installed on the left side of the material warehouse 1 and below the lifting gantry truss material taking manipulator 2, and is used for positioning and conveying the sheet materials;

[0030] The auxiliary support device 5 is fixed at the front end of the bending machine 10 to ensure that the bending quality of the longer sheet metal is not affected by its own weight and insufficient rigidity.

[0031] In an embodiment of the utility model, when the sheet material is used, the gantry truss material picking robot 2 descends above the material warehouse 1, and absorbs the first sheet material above the material warehouse 1 through the suction cup. The material warehouse 1 separates the sheets bonded together below the first sheet through the magnetic field force, ensuring that the gantry truss robot 2 takes the first sheet of material and moves it above the conveying and positioning turntable 3, and places the material on the conveying and positioning turntable 3. The conveying and positioning turntable 3 can position and convey the sheet material. After bending the sheet material, the auxiliary supporting device 5 can ensure that the longer sheet material is not affected by its own weight and insufficient rigidity in bending quality, thereby ensuring quality. After completing this bending step, the conveying and positioning turntable 3 rises and absorbs the sheet material and returns. It is determined whether the turntable needs to be rotated to another part for bending again based on the product process.

[0032] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the material warehouse 1 includes:

[0033] The material taking platform 12 is installed on the inner side of the bending machine 10. The material taking platform 12 is made of welded steel and is used for stacking sheet materials.

[0034] The magnetic plate separator 11 is installed on the material retrieving platform 12, and is used to separate the stacked plates along the vertical direction by magnetic field force when the gantry truss material retrieving manipulator 2 is ready to retrieve materials on the material retrieving platform. The gantry truss material retrieving manipulator 2 is a prior art and will not be described in detail here.

[0035] In this embodiment, the material picking platform 12 is installed on the inner side of the bending machine 10. The material picking platform 12 is made of welded steel and is used for stacking sheet materials. The magnetic plate separator 11 is installed on the material picking platform 12. When the gantry-type truss material picking robot 2 is ready to pick up materials above the material picking platform, the magnetic plate separator 11 receives a signal and separates the stacked sheets along the vertical direction through the magnetic field force to ensure that the gantry-type truss material picking robot 2 does not take away other sheets below when picking up the top sheet in the material storage, thereby preventing the sheets from being stacked and stuck together.

[0036] The magnetic plate separator 11 can be an electromagnet. When the magnetic plate separator 11 is turned on, the plate material on the surface of the material taking platform 12 can be adsorbed by magnetic force.

[0037] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the conveying and positioning turntable 3 includes:

[0038] The conveying walking mechanism 32 is slidably connected to the bending machine 10 and has a rack installed on the side;

[0039] A travel mechanism driving motor 35 is installed on the bending machine 10, and a gear is installed at the output end of the travel mechanism driving motor 35, and the gear is meshed with the rack;

[0040] A linear cylinder 331 is installed on the conveying walking mechanism 32, and the output end of the linear cylinder 331 is connected to the movable positioner 33 through a telescopic rod;

[0041] The lifting cylinder 34 is installed on the conveying walking mechanism 32 , and a vacuum suction cup 31 is installed at the output end of the lifting cylinder 34 .

[0042] In this embodiment, the conveying walking mechanism 32 is slidably connected to the bending machine 10, and a rack is installed on the side; the walking mechanism driving motor 35 is installed on the bending machine 10, and a gear is installed at the output end of the walking mechanism driving motor 35, and the gear and the rack are meshingly connected; the linear cylinder 331 is installed on the conveying walking mechanism 32, and the output end of the linear cylinder 331 is connected to the movable positioner 33 through a telescopic rod; the lifting cylinder 34 is installed on the conveying walking mechanism 32, and a vacuum suction cup 31 is installed at the output end of the lifting cylinder 34.

[0043] The conveying and positioning turntable 3 has the function of positioning plates of various specifications. When the gantry-type truss material-retrieving manipulator 2 places the plate on the conveying and positioning turntable 3, the movable positioner 33 is driven by the linear cylinder 331 to move the plate to the center of the turntable for clamping and positioning according to the different sizes of the plate, ensuring that plates of different specifications can be positioned before bending, which is the key factor for the strong adaptability of this equipment to different plates.

[0044] The conveying and positioning turntable 3 not only has the function of positioning plates of various specifications, but also can complete the functions of rotating and conveying plates to the bending machine 10, and retrieving the plates. The key lies in the conveying travel mechanism 32, which is guided by a linear guide rail, and the output end of the travel mechanism driving motor 35 drives the gear to rotate. The gear completes the linear displacement of the conveying travel mechanism 32 by meshing the transmission rack, and conveys the plate on the conveying and positioning turntable 3 that has been positioned to the bending machine 10 to complete the bending.

[0045] After the bending is completed, the vacuum suction cup 31 lifts the sheet material and sucks it tightly under the drive of the lifting cylinder 34, and then the travel mechanism driving motor 35 reverses to make the conveying travel mechanism 32 return with the bent sheet material, ready to rotate or flip for bending other parts.

[0046] The linear cylinder 331 and the lifting cylinder 34 in the conveying and positioning turntable 3 may also be replaced by an electric telescopic rod, which is not limited here.

[0047] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the auxiliary supporting device 5 includes:

[0048] The rotating shaft seat 53 is hinged on the bending machine 10, and a supporting arm 51 is installed on the side;

[0049] The turning cylinder 52 is installed on the bending machine 10 , and the supporting arm 51 is connected to the output end of the turning cylinder 52 .

[0050] In this embodiment, the rotating shaft seat 53 is hinged on the bending machine 10 , and a supporting arm 51 is installed on the side; the turning cylinder 52 is installed on the bending machine 10 , and the supporting arm 51 is connected to the output end of the turning cylinder 52 .

[0051] The auxiliary supporting device 5 ensures that the bending quality of longer sheets is not affected by their own weight and insufficient rigidity. When the blade of the bending machine 10 is pressed down, the sheet will enter the mold as the blade is pressed down and begin to bend. The sheet will flip as the bending angle changes. At this time, the flipping cylinder 51 drives the supporting arm 52 to flip and support the sheet to prevent the part of the sheet outside the mold from drooping in the direction of gravity due to gravity.

[0052] In one embodiment of the present invention, Figure 1 As shown, a flip arm 4 is installed on the right side of the conveying and positioning turntable 3, and the flip arm 4 is used to drive the sheet material to flip. In this embodiment, a flip arm 4 is installed on the right side of the conveying and positioning turntable 3, and the flip arm 4 is used to drive the sheet material to flip. A flip cylinder is installed on the conveying and positioning turntable 3, and the flip arm 4 can be hinged on the conveying and positioning turntable 3, and the flip arm 4 is connected to the flip cylinder that drives it to flip.

[0053] After completing this bending step, the vacuum suction cup 31 on the conveying and positioning turntable 3 rises and sucks the sheet material, and then the conveying and positioning turntable 3 returns under the drive of the walking mechanism. According to the product process, it is determined whether the turntable needs to be rotated to another part for bending again, or the sheet material is flipped to the other side by the right flip arm 4 for bending other parts.

[0054] The working principle of the utility model is as follows: when the sheet material is used, the gantry truss material taking manipulator 2 descends above the material warehouse 1, and absorbs the first sheet material above the material warehouse 1 through the suction cup, and the magnetic plate separator 11 in the material warehouse 1 separates the first sheet bonded together below through the magnetic field force, ensuring that the gantry truss manipulator 2 takes away the first sheet of material, and moves to the top of the conveying and positioning turntable 3, and places the material on the conveying and positioning turntable 3. The movable positioner 33 is driven by the linear cylinder 331 to move according to the sheet materials of different specifications, and the sheet material is clamped and positioned on the turntable through the displacement of the movable positioner 33. At the center of the platform, the conveying and positioning turntable 3 is driven by the conveying walking mechanism 32 to deliver the sheet to the bending machine 10 for bending. During the bending process, the driving support arm 51 in the auxiliary supporting mechanism 5 ensures that the sheet will not sag due to excessive length during the bending process, thereby ensuring the quality. After completing this step of bending, the vacuum suction cup 31 on the conveying and positioning turntable 3 rises and sucks the sheet, and then the conveying and positioning turntable 3 returns driven by the walking mechanism. According to the product process, it is determined whether the turntable needs to be rotated to another part for bending again, or the sheet is flipped to the other side by the right flip arm 4 for bending other parts.
